Introduction: Why SCOTUS Case Comparisons Matter in AP Gov

One of the most unique parts of AP U.S. Government and Politics (AP Gov) is the focus on Supreme Court of the United States (SCOTUS) case comparisons. Unlike most history courses where you memorize dates, AP Gov requires you to analyze the reasoning, constitutional principles, and precedents set by these cases.

The College Board requires students to know 15 specific SCOTUS cases, and you’ll almost certainly see at least one Free-Response Question (FRQ) where you must compare a required case to a non-required case. This skill is essential for earning top points.

This guide explains the 15 required cases, shows you how to compare them effectively, and gives strategies to score high on FRQs — with resources from RevisionDojo to make studying smoother.

The 15 Required SCOTUS Cases for AP Gov

Here are the cases you must know:

  1. Marbury v. Madison (1803) – Established judicial review.
  2. McCulloch v. Maryland (1819) – Expanded federal power (Necessary & Proper Clause).
  3. U.S. v. Lopez (1995) – Limited Congress’s commerce power.
  4. Baker v. Carr (1962) – “One person, one vote.”
  5. Shaw v. Reno (1993) – Race cannot be the primary factor in redistricting.
  6. Engel v. Vitale (1962) – Banned school-sponsored prayer.
  7. Wisconsin v. Yoder (1972) – Protected religious freedom in education.
  8. Tinker v. Des Moines (1969) – Protected student free speech.
  9. New York Times v. U.S. (1971) – Protected freedom of press against prior restraint.
  10. Schenck v. U.S. (1919) – Limited free speech during wartime.
  11. Gideon v. Wainwright (1963) – Guaranteed right to counsel in state cases.
  12. Roe v. Wade (1973) – Protected right to privacy (abortion).
  13. McDonald v. Chicago (2010) – Applied 2nd Amendment to the states.
  14. Brown v. Board of Education (1954) – Ended racial segregation in schools.
  15. Citizens United v. FEC (2010) – Protected campaign spending as free speech.

👉 AP Gov Tip: Don’t just memorize outcomes. Focus on constitutional principles (First Amendment, 14th Amendment, Commerce Clause, etc.) and how cases connect.

What Case Comparisons Look Like on the AP Exam

Example FRQ Prompt:
“In your response, use one of the required Supreme Court cases to compare with the following case: Obergefell v. Hodges (2015). Explain how both cases illustrate the Court’s role in protecting civil rights.”

How to answer:

  • Pick Brown v. Board of Education (1954).
  • Compare reasoning: Both expanded equal protection under the 14th Amendment.
  • Show understanding: Brown desegregated schools; Obergefell legalized same-sex marriage.

How to Structure SCOTUS Case Comparisons

  1. Identify the Constitutional Principle
    • Example: 14th Amendment’s Equal Protection Clause.
  2. Summarize Each Case Briefly
    • 1–2 sentences max. Don’t retell the whole story.
  3. Make the Comparison
    • Explicitly connect how each case applied the principle.
  4. Explain the Impact
    • What changed because of the ruling?

Sample Case Comparison

Case Prompt: Compare Tinker v. Des Moines (1969) with Morse v. Frederick (2007).

Answer Outline:

  • Tinker: Protected student free speech (armbands protesting Vietnam War).
  • Morse: Limited student free speech (“Bong Hits 4 Jesus” banner).
  • Comparison: Both addressed free speech in schools but reached different conclusions.
  • Impact: Shows Court balances free speech rights with school authority.

Common Mistakes Students Make

  • Writing too much case background instead of focusing on the principle.
  • Forgetting to compare — just describing both cases isn’t enough.
  • Mixing up cases with similar topics (e.g., Engel v. Vitale vs. Wisconsin v. Yoder).
  • Ignoring the impact on future law.

Real-World Case Connections

The required cases aren’t just for exams — they connect to modern issues:

  • Citizens United v. FEC (2010) → ongoing debates about campaign finance and PACs.
  • McDonald v. Chicago (2010) → state-level gun control debates.
  • Brown v. Board (1954) → continued discussions about school integration.

👉 Citing modern examples in FRQs can make your answers stronger.
